If I want to boost the power of my P200, which kit is recommended?
Malossi?
Pinasco?
Polini?
Quattrini?

I want to keep the original crank and SI 2424 carb.

I would not recommend you the Pinasco even to my worst enemies, it is a total utter piece of shit!!! I had it and it soft seized on me a half of dozen times. On its final total failure it failed on me cruising at 45 mph on 4th gear.the piston crumbled like blue cheese and the "all mighty" nickasil cylinder liners was grooved.

I have been running two brand new malossi kits on the two P200 engines that I have and so far so good. Can't complaint.

I haven't tried the Polini but I would tell you that I had a poling 177 iron kit on a Stella one time and it was a beast. You will find people on this forum that has great experiences on Pinasco and I don't doubt it.poeple will tell you that the pinasco is a good "tourer kit" , you can interpret that which ever way you want.

Good luck with your purchase, I buy all my stuff from scoowerwest in San Diego, they are very reasonable and they are true experts on vintage vespas, they should be able to answer any technical questions.

Well I'm one of 'those people', but I'll not even start to defend the Pinasco after those comments LOL.

Malossi probably does hold the crown these days, although as SDJohn and myself have found recently, you end up buying a lot of performance 'stuff' and spending a lot of time trying to get the very best out of them. My Pinasco really was plug and play by comparison and I've spent a lot of time actually riding it......or should I say 'touring'. Maybe it was just setup properly, but that would have been more luck than expertise on my part.

Safest option is to buy Malossi and the 210 Sport will serve you very well, unless you want to go nuts with an MHR or BIG with a Quattrini

^^^ and I see a lot of people like you that had no complaints. Unfortunately for me is was a deal breaker and a decisive factor on never ever get a pinasco kit in my life.

All of my 3 malossi kits have been ran pretty hard and they are taking the abuse. At the time that I started buying my malossi kits Polini didn't have the aluminum kits on the 210 cc, they came after and that is why I have malossi.

Thanks guys, I think I will go with the Malossi 210. I have a Malossi 166 fitted to my P150 for the last 8 years, and that is going like a dream. And I ride it flatout; no problems so far.

Malossi Sport, MMW head and a SIP Road, Polini BOX or FACO BOX. Bolt on and you're done. If you later want to get much more from the kit, porting, new crank, etc. is the way to go...

SaFiS, why do you suggest the MMW head rather than the Malossi one? Is it just because you prefer to have the 1.5mm stroke compensation in the head, rather than using a thick head gasket? Some other reason?

Do you guys think I need a bigger box, or will the existing one do?

When I fitted the Malossi 166, the original box choked the engine, thus I had to go for a racing exhaust.

I doubt anyone will recommend that you run a stock Piaggio exhaust with the Malossi Sport. As SaFiS said, a sporty box is a basic requirement. The question is which one? If it were me, I'd buy another Polini Original Box, as I've been very impressed with the one on my Pinasco 225. It replaced a BGM BigBox, which was also good, but the Polini just sounds so good, barely louder than stock.

Why do you prefer MMW head rather than Malossi head?

Better for touring purposes to keep things cool. The Malossi head has a "tight" squish...

yeah that stock Malossi head has too high compression ratio for average Joe tourer's bike

I could never get that Malossi 210 MHR to run right on the stock carb, then this led to the odyssey of going down the tuning rabbit hole. It was fun and I learned a lot. I still don't really know why others can run it with a few jetting changes and a stock carb, but I couldn't. I did later find out my stator was sketchy, my flywheel was sketchy, my base gasket might not have sealed well, etc. So probably the answer was in there. Also I spent a lot of time chasing a spark knock that probably was not a spark knock. If I were to do it again, I'd probably just bung a Polini 208 on there and keep it simple. Sometimes simple works. It's kind of why I'm wrestling with either tuning my smallie or leaving well enough alone and doing a simple mechanical resto on a new to me project bike.

I agree completely. I had issues with my P200 burning a hole through the top of countless pistons while attempting to run the motor in. John Gick rebuilt the original stator and replaced the CDI, and problem solved. Going forward, I switched to variable timing ignitions on all my bikes. You achieve better performance with less carnage.
